Chris Lattner c3cc71abbc Completely rewrite support for the Value::use_* list. Now, all operations on ... this list (except use_size()) are constant time. Before the killUse method (used whenever something stopped using a value) was linear time, and thus very very slow for large programs. This speeds GCCAS up _substantially_ on large programs: almost 2x for 176.gcc: 176.gcc: 77.07s -> 37.38s 177.mesa: 7.59s -> 5.57s 252.eon: 21.02s -> 19.52s (*) 253.perlbmk: 11.40s -> 13.05s 254.gap: 7.25s -> 7.42s 252.eon would speed up a whole lot more, but optimization time is being dominated by the inlining pass, which needs to be fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9160 91177308-0d34-0410-b5e6-96231b3b80d8		2003-10-16 16:53:07 +00:00
